This paper puts forward a model of the role of phosphorus in crop production, soil phosphorus dynamics and phosphorus loading that integrates the salient economic and ecological features of agricultural phosphorus management. The model accounts for the links between phosphorus fertilization,...

The Dasgupta Review takes a global perspective. Biodiversity varies geographically, and the success of biodiversity actions is sensitive to national institutional and socio-ecological conditions. Therefore, the implementation of the options for change (OCs) suggested by the Review calls for a...

This paper examines how non-binding co-operative agreements on marine fisheries management can be sustained when management plans in participating countries are implemented with error. The effects of implementation uncertainty on voluntary co-operation are compared to those of recruitment...

Agricultural production is facing high requirements on nutrient runoff reduction. Furthermore, the reductions should by done efficiently. For instance, the European Water Framework Directive calls for cost-effectiveness from schemes of measures to fulfill the target of good water quality in...

Current day large animal facilities generate more manure than they need on their own feed production areas. Excessive nutrient applications deteriorate groundwater (nitrogen) and surface water quality (nitrogen and/or phosphorus). Due to differences in environmental and economic characteristics,...

This study introduces a prototype model for evaluating policies to abate agricultural nutrients in the Baltic Sea from a Finnish national point of view. The stochastic simulation model integrates nutrient dynamics of nitrogen and phosphorus in the sea basins adjoining the Finnish coast, nutrient...

We analyze a game with N farmers that extract groundwater from a common aquifer of small storage capacity. Our aim is to compare the socially optimal, myopic and feedback extraction strategies, the latter arising from competitive interaction between extracting agents. Our extension to existing...

In this paper we address the implications of production risk for controlling fishing effort in a regulated fishery in a framework where fishers maximize expected utility of profit. We focus on controlling effort through season closures that limit the number of days the fishery is open to harvest...

This paper examines how non-binding co-operative agreements on marine fisheries management can be sustained when management plans in participating countries are implemented with error. The effects of implementation uncertainty on voluntary co-operation are compared to those of recruitment...

The paper puts forward a model of the Atlantic salmon fishery in the Baltic Sea that integrates the salient biological and economic characteristics of migratory fish stocks. Designed to be compatible with the framework used for actual stock assessments, the model accounts for agestructured...
